摘要

FLASH2 is a major extention to the soft X-ray free-electron laser FLASH at DESY. An additional variable-gap undulator line in a new separate tunnel and a new experimental hall will turn FLASH into a multi-beamline FEL user facility. Years of experience as single user facility have high impact on the planned photon diagnostics. Online measurements of intensity, position, wavelength, wavefront, and pulse length are optimized as well as photon beam manipulation tools such as a gas absorber and filters. The beamline system will be set up to cover a wide wavelength range with beamlines capable to deliver down to 0.8 nm in the 5th harmonic and 1st harmonics in the water window to cover the user community's high intrest in this wavelength range. In addition, other beamlines will cover the longer wavelengths from 6 nm - 40 nm and beyond. Proven concepts like the optical laser pump-and-probe instrument are taken over from the current operation scheme in an established way. Permanent endstations with specialized beamline layouts are foreseen. Civil construction and installations in the new FLASH2 tunnel are on-going, first beam is expected for end of 2013, and a first user experiment is anticipated for summer 2014.
